HAIR-CURLING ROD.

Application filed March 14, was. Serial No. 261.457.

Among the principal objects which the present invention has in view are: to provide rods of the character mentioned with means for quickly locking and releasing the cord winding and tightening portion of the rod; to aid in the manipulation of the rods for tightening and releasing the binder for the hair; and to simplify and. reduce the cost of the rods of the character mentioned.

Description..--The curling rod herein disclosed belongs to the type 'of irons which are employed in in'iparting to the hair what is known. as a permanent wave. As is well known, operatives when undertaking to produce the so-called permanent wave, wrap the hair very closely and tightly upon a forn'i; in the present case upon the tubular rod 15. The operation requires a mechanical stretching of the hair so that each. hair is flattened. \Vhile in this condition heat is applied to set or fix the hair in its flattened condition.

The rod herein consists of the tube 15 which is slightly tapered as seen in Figures 1 and 2 of the drawings. The tube 15 is open at both ends, the lower or smaller end neatly and snugly fitting the solid rod 16 which extends downward through the tube 15 to beyond the terminal. of the said tube, the extended end of the rod being split or bifurcated by a saw-cut 17. The cut .17 is intended to hold the free end. of the wrapping cord, later described.

At the upper end of the rod 16 it is flattened to receive the ends of spring handle blades 18. The handle blades 18 extend to and above the larger end of the tube 15. The blades 18 are provided with flat pinch handles 1.!) which are built with shoulders .20 that serve as guides to adjust the insertion of the rod 16 within the tube 15 by resting upon the ends of the said tube.

Preferably mounted 011 one of the handles 19 is a swinging latch 21. The latch 21 has at one end, a laterally extended wedgeshapcd lug 22 which when forced between the said handles .19, looks the rodin position, providing a forced frictional engagement between the blades 18 and the side of the tube 15. Then. it desired to release or turn back the rod 16, the latch 21 is turned to the position shown in Figure 1. of the drawings where the lug 22is withdrawn from between the handles 19.

When employing rods of the character constructed as herein set forth, the latch 21 primarily disposed in the position shown in Figure 2 of the drawings, thereby locking in fixed. relation the rod 16 and the tube 1.5. A strand of hair is now prepared and wound upon the tube 15 as smoothly and as tightly as the operative can. accom iilish with the hands alone. A wrapping of suitable charactor is then placed over the hair and rod to prevent any single-hairs or groups of hairs from escaping the treatment to be given. A cord or tightening member then introduced into the saw-cut 17 at the end of the rod 16 and there made fast. The cord is wrapped about the covering and carried upward towards the handles 1.9, and preferably made fast. The latch 21 is then turned to the position shown in Figure 1. where it remains. A. wrench or other suitable too] is now applied to the handle and the blades 19 thereof, and. the rod 1.6 is turned. This pulls the cord fastening device over the covering for the hair and crushes the hair and covering into firm contact with the tube 15. When su'tl icient pressure has been applied, the latch 21 is disposed in its upright position shown in Figure 2. The hair is now under intense pressure on the tube 15. The rod with its surrounding hair and covering therefor is now extended through an electric heating tube where it remains for a predetermined period of time and under certain preascertained conditions, at the end of which period, the rod is withdrawn from the heating tube and the latch 21 is thrown to its unlocking position-such as shown in Figure 1 of the drawings, and the rod 16 is then reversely rotated to unwind or release the binding cord and the covering for the hair. The hair being thus exposed is removed from the tube 15 to be further treated by the operative.

In the form of curling rod shown in Figures 6 to 9 inclusive, there is a modification of the means for preventing the backward slip of the rod 16, by a substitute for the blades 18, handles 19 and the latch 21. This substitute is an expanding spring member 23, one end of which is held by a rivet boss 24 set up from a flattened portion 25 of the rod 16. The rod 16 as is seen best in Figure 7 of the drawings is cut away to provide a recess 26 in which a boss 25L which is subsequently headed is upset by the stamping die employed to make the recess 26. The spring 23 is perforated to receive the boss 24 before the said spring is wound to the shape shown in Figure 7.

It will be seen that the free end 27 of the spring 23 is in contact with the side wall of the tube 15 with the result that instantly the rod 16 undertakes to rotate in the reverse direction, or in the direction opposite to that indicated by the arrow in Figure 7.

The end 27 engages the side wall of the tube 15 with the result that the spring 23 endeavors to expand. As, however, the said spring is resting in engagement at three points with the tube 16, the action is converted into an endeavor to expand the spring rather than to rotate the rod in the reverse direction.

When employing the rods constructed and arranged in accordance with the modified form of the invention, it becomes necessary to release the binding cord by lifting or retracting the rod 16 upward partially out of the tube 15 or until the spring 23 is lit ted above the end of the tube 15. In this position the rod 16 may be rotated. with the result that the binding cord and covering referred to above may be removed from the hair wound upon the tube 15.

Claims 1. A hair curling rod comprising a tube adapted for winding the hair thereon, a rod rotatably mounted therein, the end of the rod being extensible therethrongh and adapted to hold the end of a binding member; and means mounted on said rod for rotating and locking the same in service, said means embodying a device to prevent the retraction of said rod until released, said device consisting in resilient bi fureated handle blades rigidly attached to said rotatable member, and a wedg'ing member ex tensible between the exposed ends of said blades for spreading and maintaining them spread in contact with the sides of said tube.

2. A hair curling rod comprising an openended tubular tapered member; a solid rod extensible therethrough, the end whereof extends beyond the said tube, and bifurcated to receive and hold the end of a binding member; a plurality of resilient handle blades rigidly attached to said rod and adapted to rest upon the large end of said tube; a latch pivotally mounted on one of said blades and having a wedge-shaped lug formed at one end thereof, said lug being adapted to enter between the ends of said. blades to spread the same forcibly against the inner surface of the tube.

3. A hair curling rod comprising a cylindrical tube adapted for winding the hair thereon, a rod rotatively mounted therein, the end of said rod being extensible beyond the end of said tube and adapted for retaining the end of a binding men'iber; and means incorporated with said rod for rotating and locking the same in service, said means embodying resilient bifurcated handle blades rigidly attached to said rod, and a member extensible between the ends of said blades for spreading them to frictionally engage the sides of said tube.
